APPARATUS FOR APPLYING CAN CLOSURES.

Application filed June 14, 1920.

To all whom it may concern:

Be it known=that I, JOHN "M. Hornnr- SAL-L, a citizen of theUnitedStates, residing in Brooklyn, in the 'countylof Kings and-State of-NewYorlurhave invented anew and useful Improvement in Apparatus fori-lpplying Can Closures, of which the following is aspecification.

'This invention relates in general to devices for applying can closuresand has more particular reference to the provision of meansforapplyingclosuresto the nozzles of cans, where the nozzles have been previouslypositioned aipon the can bodies, al though it will be manifestastheinvention is better understood that it hasotherand more generalapplication.

The invention is of especial value in the closing ofnozzles on largecans of the character hereinbe-fore employed for containing varnish andthe like avherein a frangible disc of metal or other material is seatedover :the nozzle opening and seamed in suit-able fashion with theupper'open nozzle end. Prior to my present invention it has been usuallythecustom iii-sealing such nozzles with this form of closure toperformthe. operation with a hand crimper orother tool which operationis a tedious one where the output is large, and results in the formationof nozzles of varying tightness andJquality of sealing. Moreover, itfrequently deforms the nozzleand renders ithe can unsightly.

The principal object of my present invention is-the provision of meansquickly and easily operable to apply closures to the nozzles ofrelatively largecans of this: and other character.

Another important object of the invention is the provision of means forproducing nozzles of uniform satisfactory quality and pleasingappearance. A. further object of the invention isthe provisionof anapparatus of the character described consisting of few and simple partsrequiring little or no adjustment and unlikely to require frequentrepair orreplace- "merit.

Numerous other objects and advantages of the invention will be apparentas themvention is :better understood from "thefollowing descriptionwhich taken in '(30I1I16G SerialgNo. 888,780.

Thisnozzleaand closing aneans are new. and "form the subject matter of acowpen'ding applicationserialNo. 388,77 9, filed by. me on June 1i,192-0.

The nozzle 18 :isapositioned on the can prior 1 to the applicationof-the closure and is fixed inplace in any :suitableror.preferredmanner, the showing on Figure 4 in this respect being merely schematic.

The cans are filled with their content and the closure loosely laid inplace and are then dieclosed by the apparatus of the drawing. Theclosing instrumentalites coinprise a passive die arrangeable beneath thesive dies are in normal position.

shoulder 19 and an active die mounted in the die-carrier slide whichdescending presses inwardly the flange 21 and bends it in the mannershown in Figure 6, at a single operation, the while co-operating withthe passive die so that uniformity of hermetic seal results.

The passive die in the present instance comprises two movable jaws 26,pivoted at 27, upon an auxiliary housing 28, mounted on the vpresstable. This housing has an angular pocket 29 into which a verticalcorner of the can body may be thrust. The die jaws have arcuate adjacentends 31 provided with semi-circular or semi-conical pocle ets 32 adaptedto embrace the nozzles when the dies have been swung to the normalposition shown in Figure 3. Assuming the parts to be arranged as shownin this figure, the jaws tightly embrace the nozzle having an upstandingcircular wall 33 engaging beneath the shoulder 19 to support it againstthe closing action. The active die is indicated by reference character34 and has a closing recess 35 tapered on its outer side to first bendthe flange 21 inwardly, the taper continuing to a curve at the top tocurl it down over the flange 24. This is the action when the active diedescends and constitutes the entire closing operation in the presentinstance. Thereafter, the active die ascends and the can ispulled fromplace, swinging the jaws 26 to an open position by reason of the outwardmovement of the nozzle. The next succeeding can is then merely pushedinto place, its nozzle engaging the jaws 26 and moving them to theclosed position for a subsequent opera tion. Each jaw 26 has a tail 36movable beneath a guide plate 37 fixed by bolts 38 upon an upstandingcurved wall 39 at the housing, these guide plates serving also-torestrain tilting of the die jaws in the closing opera tion.

Means are provided for preventing operation of the active die exceptwhen the pas- This means in the present instance consists of a rod 41slidably mounted in hearings in the guide '37 at the right of Figure 3,in the housing and in the bed of the press, said bearings beingindicated by reference char aoters 42, 43 and 44. This rod when in nor--mal position is arranged with a reduced part 45 .in registration withthe path. of travel of a tail 36- of the right hand jaw.

alt is, however, adapted to be lowered when the treadle 26 is pressed todispose an upper part 50 of larger diameter at this path of travel andacross it. The location of the rod 41 is such, as may be observed byview ing Figure 3, that rod movement from normal position, can onlyoccur when the dies are in normal position, i. e., embracing a cannozzle. The rod 41 is connected to an arm 45 on a shaft 46 havingbearings at 47 in the press ring. The shaft 46 in turn has a second arm48 connected by rod 49 with the lever or treadle 16. As has been statedthis treadle must be depressed to produce descent of the active die 34so that the enlarged part 50 of the rod 41 prevents this operationexcept when the jaws are in normal position, because otherwise the part50 will rest on the top of the jaw and prevent any descent of the rod41. For the coupling of the rod 41 with the clutch so that they may havethe related operation above described, any well known and suitablemechanism may be employed. .1 have illustrated in Figs. 1 and 2 a rod 51which connects the treadle 16 with a clutch shifting lever 52 whichcontrols the movable element 53 of the clutch. The latter acts in aknown manner to connect and disconnect the power wheel 13 withthepress-shaft 14.

I It is thought that the invention and many of its attendant advantageswill be understood froin the foregoing without further description andit will be manifest that various changes may be made in the form,construction and arrangement of the parts without departing fromthespirit and scope of the invention, or sacrificing all of its materialadvantages the form hereinbefore described being merely a preferredembodiment.
